ver the next few decades, two emerging technologies—microfabrication and cellular engineering—will make it possible to assemble systems incorporating myriads of information-processing units at almost no cost, provided all units need not work correctly and that there is no need to manufacture precise geometrical arrangements among them. The shift to this(More)
The time-to-collision task is that of estimating the ratio of the distance of an object to the relative velocity in the direction of that object, based on time-varying images resulting from the 3-D motion of a camera with respect to the object. Traditional methods require large amounts of memory and computation time, and are not suited for real time(More)
